Virtualized Evolved Packet Core (vEPC) is a major breakthrough in network function virtualization (NFV). When
asked where they have deployed NFV in production networks, communication service providers (CSPs) consistently name vEPC as one of the top answers. Why is that?
In order to maximize their processing capacity, CSPs virtualize a subset of their network applications, including
mobile edge computing (MEC), base stations (small/macro
cells) and the mobile core, because these systems use a
large bandwidth.
The mobile packet core builds the foundation of the core
network on which mobile CSPs offer IP-based services to
their customers. Implementing vEPC solutions can help
CSPs obtain the scale necessary to accommodate growing
numbers of subscribers and large amounts of traffic or
connections while controlling costs and improving on quality of experience (QoE). In the past, evolved packet core
(EPC) solutions were deployed on purpose-built hardware.
NFV enables operators to deploy EPC c

Data is growing at amazing rates and will continue this rapid rate of growth. New techniques in data processing and analytics including AI, machine and deep learning allow specially designed applications to not only analyze data but learn from the analysis and make predictions.
Computer systems consisting of multi-core CPUs or GPUs using parallel processing and extremely fast networks are required to process the data. However, legacy storage solutions are based on architectures that are decades old, un-scalable and not well suited for the massive concurrency required by machine learning. Legacy storage is becoming a bottleneck in processing big data and a new storage technology is needed to meet data analytics performance needs.

To keep up with sweeping global economic and societal changes, public services organizations are undergoing significant technology-driven transformation. Aging populations, rapid urbanization, political instability, concerns about sustainability and resiliency, and changing worker and resident expectations are driving public services organizations to radically improve operations and service delivery. At the core of this transformation is the ability to collect and process vast amounts of data to help to improve outcomes and services. One way to generate this data is through the Internet of Things (IoT) — which IDC defines as a network of networks of uniquely identifiable endpoints or “things” that communicate without human interaction using IP connectivity. The IoT is a transformational technology that can reshape the public sector, enabling improved outcomes and new services such as remote patient monitoring, advanced traffic solutions and predictive policing.

With demand for video conferencing growing rapidly, solutions need to provide a robust, resilient, scalable, and manageable infrastructure that delivers unparalleled quality of experience. The Polycom RealPresence Platform is the software infrastructure that underlies Polycom’s video conferencing, and binds it together by integrating with core networking and security
infrastructure. This enables secure collaboration for any number of users across heterogeneous networks, with up to 50% less bandwidth consumption than other competitor solutions.
By delivering an architecture based upon open standards, Polycom has created a flexible, state of-the-art video conferencing platform that provides superior investment protection, at the lowest total cost of ownership. Download to learn more!

The role of IT is fundamentally changing from a cost-efficient enablement technology to a more strategic element of the enterprise. For companies born before the digital era, IT is a key player on their path to digital transformation; for more recent businesses designed with technology at their core, IT represents a foundational pillar on top of which everything else is built.
With this shifting role, IT’s decades-long emphasis on TCO is being eclipsed by a new-found focus on security and automation. Whether it’s the continuous risks posed by a dynamic threat landscape, the threat of digital disruption, or an inability to keep pace with the latest trends, virtually every enterprise needs to be more agile. And, with the continued evolution of compute, storage, and applications, networks have been exposed as a bottleneck to change.

As enterprise computing has evolved, businesses have been shifting to a “hybrid enterprise” where core applications and data can be located in private data centers and public clouds. The growth of hybrid cloud deployments accelerated the transition to hybrid wide-area networks (WANs). Private networks, such as MPLS, are being joined by Internet connections that offer a choice in delivery
channels—costly, but predictable, networks for mission-critical loads and cheaper public networks for bulk loads such as data backups.

Today’s networks support more applications, traffic, users, and devices than ever before – a trend that only increases on a daily basis. At the heart of all IP networks live core network services, like DNS, DHCP, and RADIUS that are crucial for keeping traffic flowing, users connected, and applications available.

Service providers around the world share concerns about running out of bandwidth. Business challenges surrounding continued bandwidth growth, linked to video, mobility, and cloud applications, are significant. Service providers also report declining revenue from a cost-per-bit perspective, so not only does the network need to grow, it also needs to grow more cost effectively.

Today the network is critical in driving change in virtually all organizations as they take their digital transformation journey. This transformation journey will help organizations increase agility, improve productivity, better engage with customers, and protect key intellectual property and assets. The network edge has a pivotal role to play in this transformation and carries perhaps the broadest set of responsibilities when compared to the core and to data center networks. As shown in Figure 1, when comparing each layer of the network, the network edge has a broad breadth of responsibility in the campus. This is also true for the branch

Core network services, which include name resolution (DNS), IP address assignment (DHCP) and management (IPAM), are used by just about every networked application, which these days includes pretty much every non-trivial application.

The bank wanted to modernize its global data center core and edge networks to move to the next stage of its private cloud journey. The bank has long recognized the advantages of server virtualization, and it wanted to move more aggressively to a software-defined data center. The bank was virtualizing all services, including compute, storage, and network, to gain greater business flexibility and deliver cost savings. But first, it needed an elastic, flexible, and production ready network to connect its data centers.
The bank wanted a dynamically scalable network to interconnect its data centers in Europe, Asia, and North America, so that it could move toward a fully automated, self provisioned cloud. The global network needed to deliver performance at scale for the company’s highly virtualized resources, while also supporting integration of legacy assets into its software-defined data centers.
